    Port Of Seattle Response Letter to Des Moines Mayor Traci Buxton: Sound Insulation Repair and Replacement Pilot Program

    The Port of Seattle wrote to Des Moines Mayor Traci Buxton in December 2025 to explain its Sound Insulation Repair and Replacement Pilot Program, a $5 million initiative aimed at helping homeowners near Seattle-Tacoma International Airport whose aging sound insulation packages may no longer be performing adequately. The program focuses on homes that received insulation before 1993 and are located within the FAA-approved Noise Remedy Boundary, with eligibility determined by acoustic testing showing interior noise levels at or above 45 dB DNL. Of the 117 homes tested in the initial phase, five were found eligible, and the Port plans to expand outreach to an additional 209 homes in early 2026 while pursuing FAA grant funding that could cover up to 80% of design and construction costs.

    City of Burien letter to Port Of Seattle Commissioners regarding failed noise insulation packages

    The City of Burien sent this October 2025 letter to Port of Seattle Commissioners demanding a new, Port-funded program to repair or replace failed noise insulation packages installed in roughly 9,400 homes near Sea-Tac Airport since the mid-1980s. The city criticizes the Port's existing pilot program (SIRRPP) as inadequate, noting that none of the 30 homes evaluated qualified for repair or replacement and that many affected homes fall outside the boundary eligible for federal funding. Burien urges the Port to stop relying on federal or state dollars and instead model a solution after San Francisco International Airport's locally funded approach.

    Update from Burien Airport Committee

    The City of Burien is calling on Port of Seattle Commissioners to overhaul their decades-old noise insulation program after hundreds of Port-installed soundproofing packages in homes near Sea-Tac Airport have degraded or failed with no repairs made. A 2024 pilot program contacted 3,000 homeowners but evaluated only 30, and none qualified for repair under the Port's narrow federal-funding criteria. Burien is urging the Port to fund a broader replacement program using its own resources, pointing to San Francisco International Airport's locally funded model as a potential template.

Sea-Tac Airport is currently undergoing the largest and longest expansion in its history, collectively known as the Sustainable Airport Master Plan (SAMP). Some of it you can already hear, but you’re probably not aware of what it all means. Here’s what you need to know.

As the source for federal transportation grants, the Puget Sound Regional Council was charged with developing a system to meet the growing need for commercial aviation. When the search for a second airport failed, they authorized the Port of Seattle to build the Third Runway, with a mandate to develop a noise abatement and mitigation program. In their effort to stop the Third Runway, the ACC argued over every detail of the Port's efforts--including property buyouts and sound insulation. The dispute was meant to be settled by a three member Expert Arbitration Panel. This is their final report. It finds 2-1, that the Port's program was insufficient in several respects. Despite that, funding for the Third Runway was approved by the PSRC, and the 'Port Package' program, proceeded largely unchanged. Expert Arbitration Panel's final decision finding that the Port of Seattle had not shown sufficient reduction in real on-the-ground noise impacts to satisfy noise reduction conditions required for approval of a third runway at Sea-Tac International Airport. The majority decision concluded the Port's noise abatement programs were insufficient despite being impressive in scope.
